FAQ:

Q: What is a step down voltage transformer?

A: A step-down transformer reduces the output voltages or in other words, it converts high voltage, low current power into a low voltage, high current power. For example, our power circuit carries 230-110v, but the doorbell requires only 16v. So, a step-down transformer should be used to reduce the voltage from 110v or 220v to 16v.

Q: What is a 110V outlet?

A: Wiring a 110V electrical outlet is a do-it-yourself task that can be completed by anyone with common tools. Modern homes all have 3-plug outlets that are comprised of a hot side, a neutral side and a ground wire.

Q: What is 110 volt?

A: When you see 110 VAC on an appliance, it means 110 volts AC power. Voltage is a measure of “circuit pressure.”. It refers to how hard the electricity pushes through a circuit. The voltage helps to determine the amperage–the amount of electricity flowing through the circuit every second.

Q: What is a power supply transformer?

A: A power supply transformer has a large number of turns on its primary coil, which is connected to the high voltage mains supply and a small number of turns on its secondary, to give a low output voltage.
